OBD2CAN RJ45

How it works

The OBDII classic adapter effectively modernizes your car's legacy OBDII interface by translating CAN OBDII queries into the appropriate legacy OBDII protocol that your ECU can understand.

This means devices expecting only a modern CAN OBDII interface can transparently work with any OBDII enabled vehicle (1996 - present).

Supported systems

• RaceCapture/Track
• RaceCapture/Pro (MK3, MK2)
• RaceCapture/Apex
• Any device that can only communicate with CAN OBDII ECUs, including some AIM devices, and others.

Optimized to get the best performance out of your ECU

The OBDII Classic adapter automatically tunes itself to get the best performance, pulling data as fast as your ECU will allow. Note, the performance will vary based on the ECU and OBDII protocol supported.

Supported OBDII protocols

J1850 PWM J1850 VPW ISO 9141-2 ISO 14230-4 CAN (pass-through)

If your car is 1996-2007, it uses one of the protocols supported by the OBDII classic adapter.

• Note: when connected to a CAN OBDII vehicle, the CAN signals are passed through, and the OBDII classic adapter is effectively bypassed.

What channels will I get?

Since the OBDII classic adapter translates any PID query it receives, you'll get whatever SAE standard channels that your car's ECU supports - channels such as RPM, Throttle Position, Engine Temperature, Manifold Pressure, Fuel Level and possibly more, depending on what your makes available.

Setup steps

• Plug the included cable into the OBDII Classic Adapter.
• Plug the other end of the cable into your RaceCapture system.
• Plug the OBDII Classic Adapter into your car's OBDII port.
• Connect the RaceCapture app to your RaceCapture unit and read the current configuration.
• Navigate to Setup
• On the CAN Bus page Turn on CAN in RaceCapture setup and choose 500KBPS for CAN 1
• On the OBDII page: Turn on OBDII, and select some initial channels. RPM, EngineTemp and TPS are recommended to start.
• Write the configuration back to your RaceCapture system.
• Start your engine and navigate to the Raw Channels page of the Dashboard view.
• Watch for your data to appear!
